Autobild Winter tyre test 2023 225/45 R18 satisfactory Ranked #16 of 20The Semperit Speed-Grip 5 secured the 16th position out of 20 competitors, earning a final rating of 'Satisfactory.' It stood out for its impressive winter capabilities and good handling on dry surfaces, alongside a remarkably high mileage.
